problem with overwrite methods

Added by Dariusz Kowalski over 10 years ago

Hello,

I am trying to write plugin which overwrite 2 methods of app/model/issue.rb

I do this like in file: https://github.com/darioo/redmine_improved_subtasks/blob/master/lib/improved_subtasks/patches/issue_patch.rb

I see that this new code is not executed and RM works as if this was not included?

What I am doing wrong?

My version of RM is 2.5.1

Best Regards
DK

Hi Dariusz,

The code you linked allows to extend the class (Add method and properties).
To override methods, you will want to use alias_method_chain.
You can check this example in which I wrap the settings action of the project controller.
alias_method_chain works as follow:
alias_method_chain :<method to override>, :<name of the override>

After that, you have to define the class method <method to override>_with_<name of the override> and you can still call the original method with: <method to override>_without_<name of the override>

Hope it helps,

Cheers,
